{"cve":"CVE-2024-20344","nvd":{"published":"2024-02-29T01:43:59.613","modified":"2026-06-17T07:06:46.140","status":"Analyzed","description":"A vulnerability in system resource management in Cisco UCS 6400 and 6500 Series Fabric Interconnects that are in Intersight Managed Mode (IMM) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on the Device Console UI of an affected device.\r\n\r This vulnerability is due to insufficient rate-limiting of TCP connections to an affected device. An attacker could exploit this vulnerability by sending a high number of TCP packets to the Device Console UI. A successful exploit could allow an attacker to cause the Device Console UI process to crash, resulting in a DoS condition. A manual reload of the fabric interconnect is needed to restore complete functionality.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-400"],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ucsfi-imm-syn-p6kZTDQC","https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ucsfi-imm-syn-p6kZTDQC"],"products":["cisco:imm_management_package"],"source":"nvd","synced_at":"2026-10-19T21:46:54.846886191+00:00"},"epss":{"cve":"CVE-2024-20344","score":0.00826,"percentile":0.57458,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
